HOT HEADS CAUSE TROUBLE-KNOW WHEN TO COOL IT: K thermocple DIY

[motoman]

Very interesting and very relevent.
Since you have collected, and have the technology to collect data, it seems to that determining the effect of ambient temp on engine temp is something we could all use.
Can you graf the effects of engine temp rise as it relates to ambient temperature rise????

I have only started comparing the Bedee oil temp gauge to the K probe, but there is disagreement already. See above . The resistor sensors are known to be non linear. My Bedee gauge is reading high on 3 tries. What is important is that it get accurate out around 280F and up. I'm still getting use to the K dipstick probe.

I have my old Intek head that pushed the guide and started all this. Plus I have a brand new head. Today I found local test lab that will run a Brinell test on both for $45. I don't know...I'm thinking about it.

My gut feeling is that the head temperature versus the ambient temperature will have a constant differential. In other words, if the ambient goes up by 20 degrees, so will the head temperature go up by roughly 20 degrees, under the same condition (loading, wind, etc.).
